THE STEREO WAS WORKING FINE BUT NOW IT ONLY SWITCHES ON FOR A FEW SECOND BEFORE SWITCHING OFF. DOESNT EVEN GIVE ENOUGH TIME TO PUT RADIO ON OR PLAY A CD. ALSO WONT SWITCH ON VIA USUAL 'ON' BUTTON BUT ONLY LIGHTS UP FOR A FEW BRIEF SECONDS WHEN THE 'DSP' OR 'MODE' BUTTON IS PRESSED. CANT UNDERSTAND IT. DID HAVE BATTERY CHANGED RECENTLY. COULD THAT HAVE UPSET IT OR IS IT JUST BROKEN, ITS MY DAUGHTERS FIRST CAR AND SHE IS REALLY UPSET AS ITS HER PRIDE AND JOY. ANY HELP, ADVICE OR EXPLANATION WOULD BE VERY MUCH WELCOMED AND APPRECIATED. THANK YOU PIPPA
